ROTARY WATER-METER.

SPECIFICATION forming part of Letters Patent No. 515,726, dated February 27, 1894.

Application tiled February 28, 1893. Serial No. 464,138. (No model.)

To 1f/ZZ whom t may concern.-

Beit known that I, Tnnonoa ZANGER, a citizen of the United States, residing at Erie, in the ccuntyot Erie and State of Pennsylvania, have invented certain new and useful Improvements in Selt-Registeri ng Dry Water-Meters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ro appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. l

My invention relates to improvements in i5 vertical self-registering dry water-meters, i. c. meters in which the water does not come in contact with the registering mechanism, placed in a separate water-tight compartment or chamber, but all arranged in one shell, 2o with the bucket-wheel upon which the water acts, so that when locked, none ot the parts can be tampered with by unauthorized persons; and the objects of the invention are to produce a meter, in which the water in its passage through its compartment is at all times separated from the registering mechanism, placed in an adjoining compartment, so that it cannot come in contact with the parts ot said mechanism, any leakage being 3o prevented by a stuffing-box between the compartments arranged side by side in one shell; also to accurately and automatically register thewater, no matter at what pressure it passes through; and finally to produce the meter at a very moderate expense and that it is not liable to get out of order.

My invention consists in the construction of certain details and arrangement of parts, as will be more fully described hereinafter 4o and speciiicallypointed out in the claim, reterence being had to accompanying drawings and the letters thereon.

Like letters indicate similar parte in the different figures of the drawings, in which Figure 1 isafront elevation of the improved dry Water-meter. Fig. 2 is a vertical section on line Fig. 3 is an enlarged detail view of the bucket-wheel and its shaft and stuffing box.

In the drawings A represents the main or outer casing or shell, made of any'castmetal and of the cross-section shown, with a partition and a head A with screw-thread, to be screwed into the main part A, which is provided at its top with the inlet nozzle a and at its bottom with the outlet nozzle a. The inlet nozzle a enters the casing at an angle, and the outlet nozzle is made much larger, so as to furnish a t'ree delivery and prevent back pressure.

Between the part A and A is placed the wheel B formed of very light sheet metal and has four or more vanes b., which are ot' semicircular shape on one side and square on the other side, and iit as closely as possible in the space in the casing, to receive said wheel and conforms in shape therewith. This wheel B is journaled on one side on a needle point c formed on the adjustable stud C in the head A, as seen in Fig. 2. At its other side is arranged a lug D, fitting into a hub a?, provided with a screw thread tc receive a screw-threaded gland CZ having a milled head, and between said gland and hub suitable packing a3 is placed, thus forming a perfectly watertight ljoint around the stud d, forming the other bearing ot the wheel B, and preventing Water interfering with, or clogging the registering mechanism with sediment, (he. Said mechanism consists ot a suitable number of toothed wheels E of the usual construction and arranged in snchmanner that the first Wheel being actuated by a linger f. on the Washer g. on the stud d will register ten gallons, the next one hundred gallons and successively one thousand, duc., which will be indicated by the pointers and dials, best seen in Fig. l. To the outlet nozzle a the receptacle G containing one or more layers or diaphragme of flannel h, is attached, through which the water will pass when the pressure is on and the meter is in operation, and it will be filtered and purified. When not in use any water not having passed through the meter will rest or lie on said diaphragms. A cover H with glass face is placed over the dial plate, to prevent tampering with the pointers.

I am aware of the Patents No. 78,795 to Flad, No. 248,194 to Meyer and Anschutz, and No. 111,040 to Buschmann, and English Pat- IOO , 5 tion of the sheliA, provided with a partitionr having hub 0,2 into which the lugfD, having f stud (Z and gland d', forming a, stuffing-box,

ts with the Wheel B, having venes b of the form showmand closely fitting the inner con- Io tour of said shell, kprovided with inlet a at its upper end and the outlet nozzle a of larger diameter, at its lower end, wth'a. registeringy mechanism, all arranged as shown'and specified.

In testimony whereof Iafx my signature in I5 presence of ktwo witnesses. f f
